Bonfire

Bonfire provides a free, web-based design editor that lets users create and sell custom merchandise across apparel, drinkware, and home goods. Pet sellers can upload animal photos or illustrations to build branded collections without upfront fees or design experience required. The platform handles production, fulfillment, and payment processing, taking a percentage of each sale instead of charging setup costs.

Ideal for pet brands, rescue organizations, and small businesses launching merchandise without design skills or inventory investment. The zero-cost entry point makes it approachable for testing pet product ideas, though the per-unit take rate may be higher than competitors charging upfront fees.
